My invention relates to vacuum cleaning apparatus, and has for its object the provision of means for rendering more efiective the operationof appliances of this class.

More particularly, my mventio'n relates to an attachable brush-member for the nozzle of a vacuum cleaner, either of the manual or wheeled type. However, since my improvements will be better appreciated asexplained in connection with the portable vacuum cleaner having supporting wheels, a

cleaning nozzle and an adjustment therefor, I may well describe said invention in connection therewith.

attachment is requisite, in connection there- By reason of the different surfaces ever which a vacuum cleaner necessarily travels and the different character. 61 dirt or refuse which must be disposed of, it is essential that the cleaning nozzle be provided with a vertical adjustment, and commonly a brushwith, for efiective work. In In use of the terms brush, brush-member or brushattachment, I refer generally to rubbing,

-brushing or similar cleaning means, as associated with the vacuum cleaning nozzle. Since the brush-attachments, moreover,

must be removed and changed, it has been my aim to provide asimple and durable type of such device, which may be readily placed upon or removed from the cleaning nozzle. The adjusting means .preferabl used herewith, are such that the nozzle 'th its attached brush, may be readily elevated or lowered with respect to the character of floor-covering with which the device is used.

Further features of my said invention or improvement will be more readily appreciated by making reference to the accompanying drawing, whereinz- Fi ure 1 is a. side elevation of a vacuum cleaning device to which my improvementsare applied; Fig. 2 is a plan view, ct-sntrally broken away, and Fig.3 an end elevah'on of vSpeciflc'ation of Letters Patent.

a' removable brushing or floor-polishin attachment of my invention; Fig. 4; is a %ragmentary view, partially in vertical section, showing a vacuum cleaning nozzle with another style of brush-attachment secured thereto; Fig. 4 is an end view of said brushattachment; Fig. 5 is a fragmentary detail also in section, illustrating the adjusting means; Fig. 6 is a lan view of the adjust able rear wheel an spring for the vacuum cleaner, and Fig. 7 is a view in elevation of referred style of adjusting screw.

'll roughout the several figures of the drawin s, I have emplogiegl the same character 0' reference, to in cate similar parts.

By referring to Fig. 1 of'the drawings, one type of portable vacuum cleaning apparatus may be explained, wherein the casing -a: contains the usual electric motor with its connected fan and terminates forwardly in v the vacuum cleaning nozzle 6. The casing is mounted upon a rear wheel 0 and two forward wheels 0'," the former being vertically adjustable on the casing. The wheel 0 is mounted within the pivoted frame 01, having a spring d which normally forces the central rib d" into engagement with the The end of said screw is groove at e, and the same is normally engaged by the rib OZ, to hold the screw in adjusted sition.

Referring now to Fig. 4, b may be assumed to comprise the nozzle of any vacuum cleaning appliance, either manual for use upon walls or hangings, or of the portable wheeled style, such as shown in Fig. 1. The

nozzle 1) has the usual transverse opening 6, whose lips b are outwardly flared, substantially as shown. Over the end of said nozzle b, there is adapted to be detachably mounted any desired brush-attachment of my invention. llhis brush-attachment comprises two longitudinal symmetrical stampings f f, unite at either end by one ormore riveted flat springs g 9. These stampings are inwardly curved at f, in order to engage the li s b, and are formed of sheet metal of en ciently heavy gage to be outwardly folded back against the felt-strips it (Fig. 3.) or other desired brush-members, as 2' (Figs. 4 and t). The extremities f of the stampings preferably are bent substantially the U-shaped brush-receiving channels and form engaging lugs which Wlll bear against the ends of nozzle b, and prevent the relative longitudinal movement'or displacement of these parts, when the brush-attachment is disposed thereon. By reason of the connect-' ing springs at either end, said brush-attachment is rendered sufliciently flexible along its median line, so that the device may be readily snapped into and out of position upon the nozzle of the vacuum cleaner.

The preferred brush-member com rises two wires 2', between which is spirallyproved brush-member of my invention very readily applied thereto when desired, which will be as easily removed therefrom for usin the cleaning nozzle alone. Moreover, by e evating or depressing the rear end of thewheeled type of vacuum cleaner, such as shown in Fig. 1, as by the adjusting screw herein shown, the nozzle with its-attached,

brush-member may be correspondingly depres sed and elevated, to suitthe conditions under which the vacuum cleaner is to be used. The two lines or rows of bristles, accordingly, may be caused to bear with the desired pressure upon the fabric or material which is being cleaned, andvserve to dislodge I the dirt, so that it may more readily be sucked up by the cleaning nozzle through,

its intermediate openingor mouth.

Having now described the preferred embodiment of my invention .or improvement,

I claim and desire to secure by Letters Patcut, the following 1. In apparatus of the class described, a

brush-attachment, comprising two parallel stampings, brush-members secured in each' of said stampings, and connecting springmembers adjacent to the ends thereof spacother, substantially as set forth.

2. In apparatus of the class described, the

combination with a vacuum cleaning nozzle having outwardly flaring .lips thereon, ofa

brush attachmenttherefor, comprising two metal stampings substantially the length of said nozzle, brush-members secured within said stampings, and terminal connecting springs spacing said stampings apart in position to register with the nozzle opening and adapting the device to be remova ly attached to said nozzle, substantially as set forth.

3. In apparatus of the class described, a

brush-attachment for suction nozzles, comprising-two parallel channeled frames, endlugs provided thereon, brush-members respectively secured therein, and flat connectin springs resiliently uniting said frames 'ad acent to their ends, adapted to retain them in their adjusted position for use, substantially as set forth.

4. In apparatus of the class described, a

brush-attachment for suction nozzles, comprising two channeled sheet-metal stampings, brush-members secured in each of said stampings; said stampings having overlapping ends to form terminal lugs, and connecting springs secured adjacent to the ends of said stampings for resiliently s acing them at a distancefrom each other, su stan-, tially as set forth.

In testimony whereof, I have affixed my signature in the presence of two witnesses.
